PfSense with transparent proxy not working
-
I suspect this has something to do with the web configurator listening on port 80 to redirect HTTP to HTTPS. I'm not aware of there being a way to disable it. I might take a look at it to see if there is an easy way to resolve this.
-
It was suggested that you may have your proxy configured on port 80. I've been informed that you do not need it to be on port 80, and if you leave it at the default port it should be fine.
-
Proxy is at the default 3128.
-
What is the output of "pfctl -sn" when you have transparent proxy enabled? And what is the date of the 2.0 BETA snapshot you are using?
-
Can yo please try the latest snapshot and got to the System->Advanced settings and check disable webConfigurator redirect?

Looking at that, you may want to disable NAT reflection instead.
-
And use split DNS instead?
-
Well try it as a test and see if it makes a difference.
If it does, perhaps the NAT reflection code may need adjusted to accommodate for this kind of scenario.
-
Hmm Split DNS does not work reliably for me so I cannot use it. It made no difference.
When I disable NAT reflection and add a domain monitoring.xxx.com to my split DNS config I get round robined between my public IP and the internal one - not matter how I flush the DNS cache or reboot:

Disabling NAT reflection was only to test whether or not your transparent proxy worked, not a test of split DNS.
Did your transparent proxy work with NAT reflection off?

I know that is why I replied:
"Hmm Split DNS does not work reliably for me so I cannot use it. It made no difference."
That referred to the transparent proxy testing.
-
That was not at all clear from what you wrote, sorry.
The output of pfctl -sn with NAT reflection disabled may help, but you might want to wait until the next snapshot (or gitsync) and try to disable the https webgui redirect.
-
Sorry if I was unclear.
Will wait for the next build and try it.
